FIELD

This disclosure is related to the general field of construction systems.In aspects, the disclosure relates to hurricane and earthquake resistantbuilding structures.

BACKGROUND

Framing in construction includes vertical and horizontal members ofexterior walls and interior partitions, both of bearing walls andnon-bearing walls. These members, referred to as studs or stick members,wall plates (top and bottom) and lintels (headers), serve as a nailing(or other fastener) base for all covering material and support upperfloor platforms, which provide lateral strength along a wall. Theplatforms may be the boxed structure of a ceiling and roof, or theceiling and floor joists of the story above. The studs give thestructure its vertical support, and the box-shaped floor sections withjoists contained within length-long post and lintels (more commonlycalled headers), support the weight of whatever is above, including thenext wall up and the roof above the top story. The platform alsoprovides the lateral support against wind and holds the stick walls trueand square. A lower platform can support the weight of platforms andwalls above the level of its component headers and joists.

Exterior wall studs are the vertical members to which sheathing andcladding are attached. They are supported on a bottom plate orfoundation sill and in turn support the top plate. Studs are commonlyspaced at 16 inches on center. This spacing may be changed; e.g., to 12or 24 inches on center, depending on the load and the limitationsimposed by the type and thickness of the wall covering used. The studsare attached to horizontal top and bottom wall plates that are often thesame width as the studs.

The floors, walls and roof of a building are typically made torsionallystable with the installation of a plywood or composite wood skinreferred to as sheathing. Spacing the framing members properly usuallyallows them to align with the edges of standard sheathing. In the past,tongue and groove planks installed diagonally were used as sheathing.Occasionally, wooden or galvanized steel braces are used instead ofsheathing. There are also engineered wood panels made for shear andbracing.

Some types of exterior sheathing, such as asphalt-impregnatedfiberboard, plywood, oriented strand board and wafer board, may provideadequate bracing to resist lateral loads and keep the wall square.Construction codes in many jurisdictions require a stiff plywoodsheathing. Others, such as rigid glass-fiber, asphalt-coated fiberboard,polystyrene or polyurethane board, will not. In these latter cases,walls have been reinforced with a diagonal wood or metal bracing insetinto the studs. In jurisdictions subject to strong wind storms(hurricane countries, tornado alleys) local codes or state law mayrequire both the diagonal wind braces and the stiff exterior sheathing,regardless of the type and kind of outer weather resistant coverings.

A multiple-stud post made up of at least three studs, or the equivalent,is generally used at exterior corners and intersections to secure a goodtie between adjoining walls and to provide nailing support for theinterior finish and exterior sheathing. Corners and intersections may beframed with at least two studs.

Roofs are usually built to provide a sloping surface intended to shedrain or snow, with slopes ranging from 1 cm of rise per 15 cm (less thanan inch per linear foot) of rafter run (horizontal span), to steepslopes of more than 2 cm per cm (two feet per foot) of rafter run. Theroof structure can be constructed from rafters and a ridge pole or nowmore commonly from pre-fabricated trusses that are assembled from stickmembers and metal connector plates to provide a ridged structure that iscapable of extending over long spans without intermediate supports. Alight-frame structure built mostly inside sloping walls comprising aroof is called an A-frame.

Light-frame methods allow easy construction of unique roof designs; hiproofs, for example, slope toward walls on all sides and are joined athip rafters that span from corners to a ridge. Valleys are formed whentwo sloping roof sections drain toward each other. Dormers are smallareas in which vertical walls interrupt a roof line, and which aretopped off by slopes at usually right angles to a main roof section.Gables are formed when a length-wise section of sloping roof ends toform a triangular wall section.

Light-frame materials are most often wood or rectangular steel, tubes orC-channels. Wood pieces are typically connected with nails or screws asfasteners. Steel pieces may be connected with nuts and bolts. Preferredspecies for linear structural members are softwoods such as spruce, pineand fir. Recently, architects have begun experimenting with pre-cutmodular aluminum framing to reduce on-site construction costs.

Intersections between portions of a framed building may be subject toshear. It has been known in the field of building construction to attachwalls and floors to the building foundation in manner conducive to holdthe building structure stable during hurricanes and/or earthquakes. Asreflected above, construction systems intended for high wind (e.g.,tornado or hurricane) prone or earthquake zones may require sufficienthorizontal support from horizontal members, sheathing, and diagonalbracing in order to stabilize the structure. Metal ties may be used toconnect frame components to the foundation. But currently there is nosystem which includes tying members spanning between sections of abuilding, between members along walls, between members around corners,members between levels, or the like to prevent damage due to shearing.

Certain terminology is used in the following description for convenienceonly and is not limiting. The words “right,” “left,” “top,” and “bottom”designate directions in the drawings to which reference is made. Thewords “a” and “one,” as used in the claims and in the correspondingportions of the specification, are defined as including one or more ofthe referenced item unless specifically stated otherwise. Thisterminology includes the words above specifically mentioned, derivativesthereof, and words of similar import. The phrase “at least one” followedby a list of two or more items, such as “A, B, or C,” means anyindividual one of A, B or C as well as any combination thereof.

Referring to FIG. 1, a shear transfer system 100 comprising a firstframing member 110, a second framing member 120, a third framing member130, a fourth framing member 140, a fifth framing member 150, and ashear tie strap 160 is shown.

The first framing member may comprise a length, a first end 112, and asecond end 113. The first framing member may be integrated in a frame104 of a framed building 105. Dashed lines at the ends of the firstframing member 110 indicate that the framing element in the framedbuilding 105 may continue on in the frame past the point where the sheartie strap is attached. The first framing member may be any elementwithin a framed building.

The second framing member 120, the third framing member 130, the fourthframing member 140, and the fifth framing member 150 may be connected tothe first framing member in the framed building, and oblique ororthogonal to the first framing member. Second, third, fourth, and fifthframing members orthogonal to the first framing member may be preferred.As illustrated in FIG. 1, these framing members are arranged orthogonalto the first framing member 110. This arrangement is, however, only onepossible arrangement. Where a framed building includes framing membersthat do not meet at ninety degree angles, these elements may still bepart of a shear transfer system herein. Alternatively, one or more ofthe second, third, fourth, and fifth framing members 110, 120, 130, 140may be blocking installed between other framing members.

The second framing member and the third framing member extend away fromthe first framing member in a first direction, leftward in FIG. 1. Thefourth framing member and the fifth framing member extend away from thefirst framing member in a second direction, rightward in FIG. 1. Whereone or more of the second, third, fourth, or fifth framing members 110,120, 130, 140 are oblique, the oblique framing members may still bereferred to as extending in either the first direction or the seconddirection. As illustrated in FIG. 1, the second framing member 120 ispositioned 180 degrees relative to the fourth framing member 140, andthe third framing member 130 is positioned 180 degrees relative to thefifth framing member 150. However, in embodiments where one or more ofthe second, third, fourth, or fifth framing members 110, 120, 130, 140are oblique, the angle between the second framing member and the fourthframing member may vary, and the angle between the third framing memberand the fifth framing member may also vary such that a cross strap 160may be positioned thereon. Whether orthogonal or oblique, thisrelationship may be described as the second framing member being opposedto the fourth framing member, and the third framing member being opposedto the fifth framing member.

The second framing member 120, the third framing member 130, the fourthframing member 140, and the fifth framing member 150 may also beintegrated in the frame 104 of the framed building 105.

The shear tie strap comprises two cross straps. As illustrated in FIG.1, the shear tie strap has a first cross strap 170, a second cross strap171, a center 172, where the two cross straps intersect or cross, andtermini at each end of both cross strap. The center 172 of the shear tiestrap may be attached to the first framing member.

The termini may be referred to as termini one 173, termini two 174,termini three 175, and termini four 176. Termini one 173 may be attachedto the second framing member 120, termini two 174 may be attached to thethird framing member 130, termini three 175 may be attached to thefourth framing member 140, and termini four 176 may be attached to thefifth framing member 150.

The portion of the shear tie strap spaced apart from the center of theshear tie strap in a first direction toward the first end of the firstframing member may be referred to a first longitudinal end 179.Likewise, the portion of the shear tie strap spaced apart from thecenter of the shear tie strap in a second direction toward a second endof the first framing member, and opposite to the first direction, may bereferred to as a second longitudinal end 180. As illustrated in FIG. 1,the termini on the first longitudinal end (termini one 173 and terminifour 176) are respectively attached to the second framing member and thefourth framing member, and the termini on the second longitudinal end(termini two 174 and termini three 175) are respectively attached to thethird framing member and the fifth framing member. Each section of ashear tie strap radiating from the center may be referred to an arm. Forexample, the shear tie strap 160, as illustrated in FIG. 1, includes afirst arm 194 radiating toward the upper left from the center 172, asecond arm 195 radiating to the lower left from the center 172, a thirdarm 196 radiating toward the lower right from the center 172, and afourth arm 197 radiating toward the upper right from the center 172.Each arm may have a different angle relative to a midline of the sheartie strap 160 through the center 172 and parallel to the first framingmember 110. Each arm may have a different twist relative to the center172 to conform to the surface of the framed building.

The frame 104 has an exterior side (upward in FIG. 1) and an interiorside (downward in FIG. 1) relative to the framed building and a sheartie strap 160 may be on either the exterior or the interior side. Asillustrated in FIG. 1, the shear tie strap 160 is attached to theexterior side of the frame 104. For convenience, sheathing is notillustrated in FIG. 1 or FIGS. 2 through 7 and 10 through 11. But theskilled artisan readily understands that framed buildings most ofteninclude sheathing and other materials attached to the frame. In anembodiment, sheathing is interposed between the shear tie strap 160 andat least one of the first framing member 120, the second framing member120, the third framing member 130, the fourth framing member 140, or thefifth framing member 150. In an alternative embodiment, the shear tiestrap 160 is between the sheathing and at least one of the first framingmember 120, the second framing member 120, the third framing member 130,the fourth framing member 140, or the fifth framing member 150.

A shear tie strap in a shear transfer system may comprise fastenerstrips comprising fastener engagement areas to attach the shear transfersystem to framing members. The fastener strips may be adapted to receiveany type of fastener to fix a shear tie strap to framing members. In anembodiment, the fasteners are nails and the fastener strip may bereferred to as a nailer strip or nailing strip. The fastener engagementareas may be holes through which nails may be driven. A fastener stripmay include one or more fastener engagement areas. A shear transfersystem may include at least one fastener that attaches the shear tiestrap to framing members. FIG. 1 illustrates the shear tie strap 160with fastener strips 191, 192, 193, and 194 (dots representing fastenerengagement areas) located at the termini 173, 174, 175, and 176,respectively. Shear tie strap 160 is also illustrated with a fastenerstrip (a dot) at the center 172. A variety of different configurationsof fastener strips and numbers of fastener engagement areas may beprovided. One variation from the shear tie strap 160 may be to includemultiple fastener engagement areas around the center 172.

A shear transfer system may include a shear tie strap comprising atleast one connecting strap. As illustrated in FIG. 1, the shear tiestrap 160 includes two connecting straps. A first connecting strap 181extends over the first framing member 111 and connects the cross straps(through connection with termini 173 and 176) on the first longitudinalend 179 of the shear tie strap 160. And a second connecting strap 183extends over the first framing member 111 and connects the cross strapson the second longitudinal end 180 of the shear tie strap 160. Aconnecting strap may be at the termini of cross straps, as illustrated,or at an intermediate position between the termini at one end of a sheartie strap and the center. The embodiment illustrated in FIG. 1 includestwo connecting straps. But a shear tie strap may have no connectingstrap. A shear tie strap may include one connecting strap between anytwo neighboring termini. A shear tie strap may include three connectingstraps, connecting all but one of the neighboring termini. A shear tiestrap may also include four connecting straps, connecting all four ofthe neighboring termini, as discussed in connection with anotherembodiment of the shear transfer system, below.

As illustrated in FIG. 1, both of the first connecting strap 181 and thesecond connecting strap 182 are at the respective termini on the firstlongitudinal end and the second longitudinal end, and comprise one ormore fastener strips. A connecting strap may include one or morefastener strips.

A shear tie strap in a shear transfer system may be one integral unitcomprising a first cross strap, a second cross strap, and any connectingstraps that may be present. A shear tie strap in a shear transfer systemmay be comprised of separate parts that are fixed to one another. Ashear tie strap in a shear transfer system may be comprised of acombination of integral components forming an integral unit and one ormore separate parts fixed to the integral unit.

The shear transfer system illustrated in FIG. 1 may be adapted to a widevariety structures in a framed building. The representation in FIG. 1appears planar, and the shear transfer system may include a planar sheartie strap attached to framing members within the same plane. However, ashear transfer system may include a shear tie strap where each arm isangled to conform to the surface of the framed building upon which it isattached. For example, the shear tie strap 160 may include the first arm194 and the second arm 195 at a 90 degree angle with respect to thethird arm 193 and the fourth arm 194 when the center 172 is positionedat a 90 degree corner of a framed building.

Shear tie straps and shear tie systems implementing the shear tie strapsare described in PCT/US15/21456, which was filed Mar. 19, 2015, wastitled Shear Tie System For Vented Roof Ridge, and is incorporatedherein by reference as if fully set forth. Any shear tie strap thereinmay be in a shear transfer system herein.

FIGS. 8 and 9 illustrate shear tie straps that may be provided as ashear tie strap in a shear transfer system herein. A shear tie strap 830(FIG. 8) or a shear tie strap 930 (FIG. 9) may take the place of anyshear tie strap in a shear transfer system described herein. The shearties straps illustrated in FIGS. 1, 8, 9, and 10 are merely exemplary.Modifications of a shear tie strap within the spirit of the disclosureherein are contemplated in embodiments herein.

Referring to FIG. 8, a shear tie strap 830 is illustrated. The shear tiestrap of FIG. 1 or FIG. 10 may be replaced with any similar structureproviding a generally “X” shaped configuration. The shear tie strap 830may be connected to a first framing member, a second framing member, athird framing member, a fourth framing member, and a fifth framingmember, and to sheathing. Non-limiting examples of these members areillustrated with reference to FIGS. 2 through 7 and 11.

A shear tie strap may be formed of a stamped sheet metal body. Asillustrated in FIG. 8, the body 840 of the shear tie strap 830 includescross straps 842 in order to transfer shear forces across a firstframing member that the shear tie strap is attached to from onelongitudinal end of the shear to strap to on the opposite longitudinalend; and thereby from one set of framing members to another. Nailerstrips 844 are provided at the termini of and connect these cross straps842, and a center nailer strip 846 is provided with an enlarged area forconnection to the first framing member 816. Preferably holes 848 arepre-formed in the stamped sheet metal body 840 for the shear tie strap830. These can be punched at the same time that the sheet metal body 840is punched or can be drilled or punched afterwards in a separate step.While a representative pattern for these pre-formed holes 848 is shown,those skilled in the art will recognize that other patterns can be used.

As shown in FIG. 8, preferably the shear tie strap 830 has a width Xthat is designed to extend between adjacent framing members 814. In anembodiment, this dimension is 17.5 inches or 25.5 inches in order toallow the shear tie strap 830 to span adjacent members 814 that arelocated at 16 inches on center or 24 inches on center. However, otherwidths can be provided in order to accommodate the spacing betweenframing members 814.

The shear tie strap 830 may be installed using nails or screws betweenadjacent framing members 814 and may be connected to the first framingmember 816 as well. Depending upon the shear loads anticipated due toeither earthquake or wind (for example, hurricane) conditions, the sheartie straps 830 can be located between contiguous pairs of framingmembers 814 along a framed building, or can be spaced apart further, asrequired.

In an embodiment, the shear tie strap 830 is punched from 20 gauge sheetmetal. However, other thicknesses of sheet metal can be utilized,depending upon the loads required for the particular application.

Blocking 850 can be installed between the adjacent members 814 in aposition aligned with the nailer strip ends 844 of the shear tie strap830.
